Gmail's spam filter is pretty good at keeping junk out of my Inbox. But recently I noticed spams not in my Inbox but in my Sent Mail folder. How can I stop this from happening?

The same thing has happened to me (see screenshot). Turns out if a spammer sets the message's From: address to the To: address (both of which are you), Gmail doesn't spam filter it; instead, it files it in Sent Mail automatically even though YOU didn't send the message.

You can set up a filter to delete all messages with a specific matching To: and From: address, but that means you couldn't ever send yourself a message to the same address. Anybody else got a better idea? Let us know in the comments or to tips at lifehacker.com. — Gina Trapani
